Abstract
AbstractThe effect of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), infestation on the quality of sweet cherry, Prunus avium (L.) L., fruit was studied. Each cherry was infested with one first instar codling moth and held at 3.3C for 0 (control), 1, 2, 4, 7, 10, or 14 days. After cold storage, fruits were maintained at 25C and observed periodically for damage using a visual scale from 0 as no damage, to 9 as complete destruction. Two groups of ‘Bing’ cherries were examined, one from an organically grown orchard and the other from a commercial orchard with conventional chemical control. Uninfested fruits maintained quality for one month at 25C whereas infested fruits had a damage rating of 2 by the fifth day. Infested organic fruits deteriorated faster than the conventional cherries. Larvae were often not detected because of fruit deterioration and fungal contamination. Fruit quality deterioration due to codling moth infestation is an important component of the Systems Approach for quarantine security for cherries exported to Japan. Infested fruit would rapidly deteriorate as the result of decay and be culled at time of packing.
